Based on who you ask, YouTube's thumbnail preview that automatically plays videos while scrolling is either a blessing or a curse. The feature allows users to take a sneak peek at the video's content while hovering over the thumbnail. However, not everyone likes to see a dynamic video while scrolling through the feed. It gets even more annoying on mobile, where you can scrub through the video and activate the audio from the thumbnail preview that plays automatically. So, if you are someone who wants to stop YouTube videos from playing while scrolling, here's how to turn off thumbnail preview on YouTube.

1. Open the YouTube app on your phone and tap the profile icon in the top right corner. Now select “Settings” to access the YouTube settings.

2. Tap "General" under Settings and select "Playback in Feeds" to control autoplay of the YouTube home feed.

3. From the popup window that appears, choose to turn off playback in feeds, and that's it. The video thumbnails will no longer auto-play as you scroll through the feed.
